标题： Spin pumping driven by magnon-polaritons in a ferromagnet-coplanar superconducting resonator hybrid system

摘要： 我们展示了一种由强耦合的磁振子-光子系统驱动的自旋泵浦现象，该现象使用了铁磁体与共面超导谐振器杂化系统，在1.4 K的温度下进行。 通过反向自旋霍尔效应的电读出揭示了模式分裂和线宽展宽等特征耦合特性，证明了强耦合微波光子和磁振子的电检测。 通过结合自旋泵浦和反向自旋霍尔效应测量得到的磁振子-光子耦合强度与微波传输实验的结果进行了比较。 此外，依赖于微波功率的测量显示，在超过某一临界微波功率阈值时，随着微波功率的增加，耦合强度减小，并且超导谐振器开始出现非线性效应。 显示英文摘要

摘要： We demonstrate spin pumping driven by a strongly coupled magnon-photon system using a ferromagnet-coplanar superconducting resonator hybrid system at 1.4 K. Electrical readout via the inverse spin-Hall effect reveals characteristic coupling features, including mode splitting and linewidth broadening, demonstrating the electrical detection of strongly coupled microwave photons and magnons. The magnon-photon coupling strength obtained by combined spin pumping and inverse spin-Hall effect measurements is compared to microwave transmission experiments. Furthermore, microwave power-dependent measurements reveal a decrease in the coupling strength with increasing microwave power alongside the onset of nonlinearities of the superconducting resonator above a critical microwave power threshold.
